We’ve always been taught that we breathe in oxygen and take out carbondioxide. If we exhale carbondioxide, then how would mouth-to-mouth resuscitation work? or wouldn’t the candle just blow off, if u are next to it.

I am certain that we breathe in air (and not oxygen), need to figure out what is the composition of our breath when we exhale.

Your exhaled breath is not pure carbon dioxide – your body isn’t able to absorb all the oxygen you breathe in. The air you breathe in has about 20% oxygen, the air you breathy out still has about 15% oxygen

Like other things in life, breathing isn’t that simple. What we breathe in is far from pure oxygen, but roughly by volume 78 per cent nitrogen, 21 per cent oxygen, 0.965 per cent argon and 0.04 per cent carbon dioxide (plus some helium, water and other gases). The permanent gases in air we exhale are roughly 78 per cent nitrogen, 15 to 18 per cent oxygen (we retain only a small amount), 4 to 5 per cent carbon dioxide and 0.96 per cent argon, the CO2 being of course used by plants during photosynthesis.

So what’s this blog about?

Another attempt? Well yes. Attempting to figure out another sustainable model (there are some other attempts going on parallel-ly).
Well, we have a lot of questions in mind. we read up stuff, we do some research to find answers to these questions. This is an attempt to publish that little 15-20 minute research.
